VidePak’s mesh PP bags achieve ≤0.2 mm dimensional tolerances and 98% color accuracy across Pantone, CMYK, and RAL systems, ensuring superior durability and branding precision for agricultural, construction, and retail applications. With ISO 9001-certified quality protocols and 30+ years of expertise, we deliver defect rates below 0.5% while supporting full-surface printing, UV-resistant coatings, and custom weave densities.
1. The Science of Mesh PP Bag Manufacturing
Mesh polypropylene (PP) bags are woven from extruded monofilaments, creating breathable yet robust structures ideal for storing bulk materials like onions, potatoes, or construction sand. VidePak’s production integrates Austrian Starlinger circular looms and AI-driven inspection systems to guarantee:
- Weave Consistency: 12×12 to 16×16 strands per inch, adjustable for 0.5–10 mm mesh sizes.
- Tensile Strength: 1,200–1,800 N/5 cm (ASTM D5035), outperforming industry averages by 25%.
- Thickness Control: ±0.05 mm tolerance via laser micrometers.
A 2023 case study showed a Dutch onion supplier reduced spoilage by 18% using our 8×8 mesh bags with antifungal coatings and 360° ventilation.
2. Customization Capabilities
Structural Adaptations
| Parameter | Range | Compliance Standard |
|---|---|---|
| Bag Dimensions | 30×50 cm to 120×180 cm | ISO 4591 |
| Mesh Size | 0.5–10 mm | ASTM D1777 |
| Fabric Weight | 80–150 g/m² | ISO 536 |
| Handle Strength | 15–30 kg | EN 13590 |
Printing Excellence
- Full-Surface Coverage: 8-color flexographic printing achieves 1440 dpi resolution, covering 100% of bag surfaces without gaps.
- Color Systems:
- Pantone Matching: ΔE ≤1.5 using X-Rite spectrophotometers.
- UV Inks: Retain 95% chromaticity after 1,500 hours (ISO 4892-3).
- Abrasion Resistance: Prints withstand 500+ cycles of ASTM D5264 rub testing.
For example, a UAE construction firm enhanced brand visibility using our RAL 3020-red printed mesh bags with QR codes for asset tracking.
3. Quality Control Protocols
VidePak’s 16 extrusion lines and 100+ Starlinger looms enforce 12-stage inspections:
Key Testing Metrics
- Tear Resistance: >35 N (Elmendorf method, ASTM D5884).
- Seam Integrity: Stitching withstands 80% of fabric strength (ISO 13934-1).
- UV Aging: <5% strength loss after 2,000-hour xenon exposure.
- Grammage Checks: ±1.5% variation via ISO 536 gravimetric analysis.
Additional inspections include:
- Edge Smoothness: Microscopic analysis to eliminate >0.1 mm fibrils.
- Color Fastness: 72-hour salt spray testing (ASTM B117) for coastal applications.
4. Technical Specifications
